Optimization of Venting Units to Minimize the Dimensions of Explosive Zones

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT This contribution investigates how changes of standardized venting geometries affect the EX zone extension. CFD simulations are used to explore different venting unit geometries in order to reduce the experimental effort. The optimization of the venting unit geometries is analyzed separately from the dispersion of the hydrogen–air mixture into

Impacts of Pasture Conversion to Sugarcane on Water Fluxes and Water Use Efficiency in the Southeastern US

GCB Bioenergy, Volume 18, Issue 9, September 2026.
Sugarcane expansion, poised to reshape the Southeastern US bioenergy landscape, has uncertain ecohydrological implications following pasture conversion. Compared with improved and semi‐native pastures, sugarcane showed more conservative water use, stronger stomatal sensitivity to atmospheric water demand, higher evaporation, and greater water‐use ...

Sudden Variation Effect of Aerodynamic Loads and Safety Analysis of Running Trains When Entering Tunnel Under Crosswind

Applied Sciences, 2020
Sudden variation of aerodynamic loads is a potential source of safety accidents of high-speed trains (HSTs). As a follow-up investigation on the aerodynamic response of a HST that enters a tunnel under crosswind environment, this paper focuses on the ...

Geography and ‘The New’

Transactions of the Institute of British Geographers, Volume 51, Issue 3, September 2026.
ABSTRACT This Intervention reflects on the multiple, contradictory and ambivalent relations human geography has with ‘the new’. Some sort of relation with the new is an inescapable and necessary part of all practices of knowledge generation. Newness, whether it be an empirical finding, an idea, a concept or an approach, can fuel the interest, wonder ...

The Influence of Aged Smoke on Urban Ozone: Aircraft Measurements in Chicago During the 2023 Canadian Wildfires

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract As large wildfires become more frequent and severe in North America due to heightened fuel aridity and fire weather conditions driven by anthropogenic climate change, wildfire smoke has an increasingly important influence on air quality. Transported smoke can impact urban boundary layer ozone (O3) directly, via the entrainment of O3 formed in ...

Optimized Design and Numerical Analysis of Dust Removal in Blast Furnace Nozzle Based on Air Volume-Structure Coordinated Control

Atmosphere
Blast furnace tuyeres are the primary dust emission source in ironmaking facilities (accounting for over 30% of total pollutants). High-temperature dust plumes with intense thermal energy are prone to dispersion, while China’s steel industry ultra-low ...

Neutral Wind Dynamics in High‐Latitude Regions During the 17 March 2013 Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Neutral winds play a critical role in transporting mass, momentum, and energy throughout the upper atmosphere. During geomagnetic storms, momentum is transferred to the thermosphere primarily through ion–neutral collisions, along with other forces. This study investigates high‐latitude neutral wind dynamics during the 17 March 2013 storm using
